September 2008 Briefing - Radiology
Here are what the editors at HealthDay consider to be the most important developments in Radiology for September 2008. This roundup includes the latest research news from journal articles, as well as the FDA approvals and regulatory changes that are the most likely to affect clinical practice.
News Media Under-Report Drug Company Funding of Research
TUESDAY, Sept. 30 (HealthDay News) -- Reports on medication research published in general news media often fail to disclose that the research received pharmaceutical company funding and frequently refer to drugs by brand name rather than using the generic name, according to an article published in the Oct. 1 issue of the Journal of the American Medical Association.
Post-Surgical Risks Analyzed in Aortic Dissection
THURSDAY, Sept. 25 (HealthDay News) -- In patients with acute type B aortic dissection, a large maximal false lumen area and a higher branch-vessel involvement greatly increase the risk of in-hospital post-surgical complications, according to research published in the Sept. 30 issue of the Journal of the American College of Cardiology.
Racial Discrepancies Exist for Asymptomatic Colon Polyps
TUESDAY, Sept. 23 (HealthDay News) -- Black patients undergoing colonoscopy reveal a higher prevalence of polyps compared to white individuals, according to data reported in the Sept. 24 issue of the Journal of the American Medical Association.
Radiosurgery May Benefit Patients with Spinal Tumors
MONDAY, Sept. 22 (HealthDay News) -- Radiosurgery for spinal and paraspinal metastases is a relatively new treatment that provides a minimally invasive option for pain relief and tumor control, according to a review in the August issue of Neurosurgical Focus.
Stomach Treatment Reduces Ghrelin, Limits Weight in Pigs
MONDAY, Sept. 22 (HealthDay News) -- Embolization of gastric arteries in swine resulted in lower levels of ghrelin -- a hormone that can stimulate food intake -- and less weight gain in following weeks compared to control animals, according to research published in the October issue of Radiology.
Antibiotic Resistance Has Become a Global Pandemic
FRIDAY, Sept. 19 (HealthDay News) -- A concerted international and national response, behavior change by consumers and providers, and the development of antibacterial agents are all urgently needed to tackle the global problem of rapidly increasing antibiotic resistance, according to an article published online Sept. 18 in BMJ.
MRI Can Detect Carotid Plaque Hemorrhage
THURSDAY, Sept. 18 (HealthDay News) -- MRI offers a non-invasive method of assessing intraplaque hemorrhage in carotid arteries to identify patients at greater risk of atherosclerotic disease, according to a report in the October issue of Radiology.
History, Physical Exam Provide Accurate Cardiac Estimates
THURSDAY, Sept. 18 (HealthDay News) -- Estimates of hemodynamic parameters from a history and physical exam are largely accurate and can predict death or rehospitalization in patients with advanced heart failure, according to study findings published in the September issue of Circulation: Heart Failure.
CT Colonography Sensitive for Large Adenomas
WEDNESDAY, Sept. 17 (HealthDay News) -- Computed tomographic (CT) colonography is a sensitive method for detecting large adenomas and cancers in asymptomatic adults, while individuals negative for adenomas are at low risk of developing cancers five years later, according to two studies published in the Sept. 18 issue of the New England Journal of Medicine.
Screening May Point to Lung Cancer Before Symptoms Arise
WEDNESDAY, Sept. 17 (HealthDay News) -- Diagnosing lung cancer before symptoms become evident may be possible by screening for autoantibodies to particular antigens, according to research published online Sept. 15 in the Journal of Clinical Oncology.
MRI Improves Diagnosis in Children with Hearing Loss
WEDNESDAY, Sept. 17 (HealthDay News) -- An abnormal cochlea and abnormal cochlear nerve are the most common inner ear abnormalities in sensorineural hearing loss (SNHL), and inner ear abnormalities are more common among patients with severe and profound SNHL and in children with unilateral hearing loss, according to a report in the September issue of the Archives of Otolaryngology -- Head & Neck Surgery.
3-T MRI Holds Advantage in Epilepsy Assessment
FRIDAY, Sept. 12 (HealthDay News) -- MRI at 3 T was associated with better rates of lesion detection and accurate assessment of lesions than 1.5-T MRI in evaluating epilepsy, according to research published in the September issue of the American Journal of Roentgenology.
Shortage of Nuclear Imaging Agents May Delay Scans
MONDAY, Sept. 8 (HealthDay News) -- Heart imaging, bone scans and some cancer detection tests may be subject to delays or even cancellation due to a global shortage of medical isotopes, according to a letter and article published online Sept. 5 in BMJ.
Imaging Often Changes Colorectal Cancer Management
TUESDAY, Sept. 2 (HealthDay News) -- The results of positron emission tomography (PET) scanning often changes disease management in patients with suspected colorectal cancer recurrence and can identify those whose disease is more likely to progress, researchers report in the September issue of the Journal of Nuclear Medicine.
